One Piece is the Rio Poneglyph: It might contain the Rio Poneglyph, but it IS not the Rio Poneglyph. However there should be just a bit of treasure to keep Nami happy :)

Smoker is going to take care of Luffy's kid: Luffy's life doesn't have to mirror image Roger's. I don't think he is going to marry at all!

I don't think Luffy is going to lead a war against the World Government. Instead, I think he is going to stop the war like Shanks and rebuild the world Government. In the process, probably defeat Akainu who doesn't want the war to be stopped and wants to destroy all pirates.

Yup, that's all so hope you guys enjoyed it and please leave your comments!
